Free Vibration Analysis of Delaminated Composite Plates Using Finite Element Method.

In the present paper equivalent single layer (ESL) theory has employed with finite element method to describe the free vibration analysis of delaminated composite plates. Based on the first order shear deformation theory (FSDT) and finite element formulation, the work is fully concentrated on the free vibration analysis of delaminated composite plates. Two types of boundary conditions which are simply supported (S-S-S-S) and cantilever type (C-F-F-F) have taken for the analysis. The present work has also calculated the deformation at different places in composite plate; this is fully analytical and computational approach. Result is validated with the various references presented on the literature survey [ABSTRACT FROM AUTHOR]
